Possible Causes

How to Fix / Troubleshooting
Safety first: Remove the battery before inspecting terminals or opening the housing.
Steps to try:
- Check battery fit: Ensure the battery slides fully into the compartment and locks. Wiggle gently to see if there is play; excessive movement can cause intermittent power.
- Inspect terminals: Look for bent, recessed, or burnt terminals on both the battery and vacuum. Clean with a dry cloth.
- Test with another battery: If available, try a different Eureka battery. If the issue disappears, replace the original battery.
- Inspect PCB (advanced): If a good battery still results in dim LEDs and random shutoffs, open the housing and inspect the main PCB for burnt components or bulging capacitors. Replace the PCB if damaged.
